Resumo: | Delayed harvesting may affect the physiological quality of soybean seeds, due to adverse conditions in the field. This study aimed to evaluate the physiological and sanitary quality of soybean seeds (BRS 820 RR® cultivar) harvested at eight periods (0; 5; 10; 15; 20; 25; 30; and 35 days after the R8 phenological stage - full maturity) and stored for two periods (0 and 8 months). The following evaluations were carried out: moisture content, germination and emergence rate, emergence speed index, total plant dry mass, accelerated aging, electrical conductivity, mechanical damage, vigor and viability (tetrazolium) and sanitary quality of the seeds. The delayed harvesting of soybean seeds from 10 days after R8 impairs seed vigor and germination, in addition to increase the incidence of pathogens. Regardless of the harvesting period, the soybean seeds stored for eight months showed a reduction in their physiological quality, with an increase in the incidence of Phomopsis spp. |

Objetivou-se avaliar a qualidade fisiológica e sanitária de sementes de soja (cultivar BRS 820 RR®) colhidas em oito épocas (0; 5; 10; 15; 20; 25; 30; e 35 dias após o estádio fenológico R8 - maturação plena) e armazenadas por dois períodos (0 e 8 meses). Foram efetuadas as seguintes avaliações: grau de umidade, taxa de germinação e emergência, índice de velocidade de emergência, fitomassa seca total da planta, envelhecimento acelerado, condutividade elétrica, dano mecânico, vigor e viabilidade (tetrazólio) e qualidade sanitária das sementes. O retardamento na colheita de sementes de soja a partir de 10 dias após R8 prejudica o vigor e a germinação das sementes, além de aumentar a incidência de patógenos. Independentemente da época de colheita, o armazenamento das sementes de soja por oito meses culminou em redução na sua qualidade fisiológica, com incremento na incidência de Phomopsis spp.Escola de Agronomia - Universidade Federal de Goiás2017-09-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/47576Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 3, Jul./Sep. 2017; 312-320Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 3, jul./set. 2017; 312-320Pesquisa Agropecuária Tropical; v. 47, n. 3, jul./set. 2017; 312-3201983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/47576/24331Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessZuffo, Alan MarioZuffo Júnior, Joacir MarioZambiazzi, Everton ViniciusSteiner, Fábio2020-07-13T18:45:13Zoai:ojs.revistas.ufg.br:article/47576Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:17.494520Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
